kyFast, Effective Impact CleaningAlfa Laval TJ TZ-79 Rotary Jet Head

.

ApplicationThe Toftejorg TZ-79 rotary jet head provides 3D indexed impactcleaning over a defined time period. It is automatic and represents aguaranteed means of achieving quality assurance in tank cleaning.The device is suitable for processing, storage and transportation tanksand vessels between 250 and 1.250 m3. Used in breweries, food anddairy processes and many other industries.

Working principleThe flow of the cleaning fluid makes the nozzles perform a gearedrotation around the vertical and horizontal axes. In the first cycle, thenozzles lay out a coarse pattern on the tank surface. The subsequentcycles gradually make the pattern more dense, until a full pattern isreached after 8 cycles.

Cleaning Pattern

First cycle Full pattern

The above drawings show the cleaning pattern achieved on acylindrical horizontal vessel. The difference between the first cycle andthe full pattern represents the number of additional cycles available toincrease the density of the cleaning.

Standard DesignThe choice of nozzle diameters can optimise jet impact length and flow rate at the desired pressure. Selfcleaning arm available. As standarddocumentation, the Toftejorg TZ-79 can be supplied with a “Declaration of Conformity” for material specifications.

TRAX simulation toolTRAX is a unique software that simulates how the Toftejorg TZ-79 performs in a specific tank or vessel. The simulation gives information on wettingintensity, pattern mesh width and cleaning jet velocity. This information is used to determine the best location of the tank cleaning machine and thecorrect combination of flow, time and pressure to implement.

A TRAX demo containing different cleaning simulations covering a variety of applications can be used as reference and documentation for tank cleaningapplications. A TRAX simulation is free and available upon request.
